Abstract

A process for operating a fuel cell installation and a fuel cell installation for carrying out the process include at least one fuel cell block. A process gas for the fuel cell block is fed into the fuel cell block with a liquid ring compressor. In this way, the process gas is humidified at the same time as it is compressed, thus using the compression heat simultaneously as evaporation enthalpy, as well as the heat from the cooling circuit of the fuel cell stack.
